Molecular evidence for a relationship between LINE-1 elements and X chromosome inactivation: the Lyon repeat hypothesis. Hurst LD Is Stellate a relict meiotic driver? Heterochromatin, Small RNAs, and Genetic Conflict Most of the cellular phenotypes described above—at least, those described in Drosophila species—suggest a failure in the chromatin state regulation.
The X chromosome resembles a large autosomal chromosome with a long and a short arm. Ever since the discovery of X-inactivation through research into Calico cats, it has been postulated that X-inactivation plays a role in genetic sex determination in humans.

Autosomes: Autosomes are labeled with numbers, from 1 to Dominant inheritance occurs when an abnormal gene from one parent causes disease even though the matching gene from the other parent is normal.
Sex chromosomes have evolved independently across many plant groups. The members of the autosome pairs are truly homologous; that is, each member of a pair contains a full complement of the same genes albeit, perhaps, in different allelic forms.

Apr 28, · Sex Chromosomes Definition. Sex chromosomes are chromosomes that determine whether the individual is male or female. Though these two chromosomes pair with each other during meiosis, there is usually very minimal homology or recombination between them, primarily because of a large difference in their genetic content and 51digg.info one chromosome is smaller, and appears to .

The sex chromosomes have evolved from a pair of autosomes within the last 2), and the sequence therefore covers at least % of the X chromosome euchromatin.
